一、單作(zuo)用葉片泵(beng)的工作(zuo)原(yuan)理: ATOS葉(xie)片(pian)泵(beng)由轉(zhuan)(zhuan)子(zi)(zi)1、定(ding)子(zi)(zi)2、葉(xie)片(pian)3、配(pei)(pei)油(you)盤(pan)和(he)(he)端蓋等部(bu)件所組成。定(ding)子(zi)(zi)的(de)(de)(de)內(nei)表面(mian)是(shi)(shi)(shi)圓柱形(xing)孔(kong)。轉(zhuan)(zhuan)子(zi)(zi)和(he)(he)定(ding)子(zi)(zi)之間存在(zai)(zai)(zai)著偏(pian)心。葉(xie)片(pian)在(zai)(zai)(zai)轉(zhuan)(zhuan)子(zi)(zi)的(de)(de)(de)槽內(nei)可靈活滑動(dong),在(zai)(zai)(zai)轉(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)動(dong)時(shi)的(de)(de)(de)離心力(li)以及(ji)通(tong)入葉(xie)片(pian)根部(bu)壓(ya)力(li)油(you)的(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下,葉(xie)片(pian)頂部(bu)貼緊在(zai)(zai)(zai)定(ding)子(zi)(zi)內(nei)表面(mian)上,于(yu)是(shi)(shi)(shi)兩相鄰葉(xie)片(pian)、配(pei)(pei)油(you)盤(pan)、定(ding)子(zi)(zi)和(he)(he)轉(zhuan)(zhuan)子(zi)(zi)間便形(xing)成了一個個密封(feng)的(de)(de)(de)工作(zuo)(zuo)腔。當轉(zhuan)(zhuan)子(zi)(zi)按逆時(shi)針(zhen)方(fang)向旋轉(zhuan)(zhuan)時(shi),圖右側的(de)(de)(de)葉(xie)片(pian)向外伸(shen)出(chu),密封(feng)工作(zuo)(zuo)腔容積(ji)逐漸(jian)增大,產生真空,于(yu)是(shi)(shi)(shi)通(tong)過吸油(you)口(kou)(kou)6和(he)(he)配(pei)(pei)油(you)盤(pan)5上窗(chuang)口(kou)(kou)將油(you)吸入。而在(zai)(zai)(zai)圖的(de)(de)(de)左側。葉(xie)片(pian)往里縮進,密封(feng)腔的(de)(de)(de)容積(ji)逐漸(jian)縮小,密封(feng)腔中的(de)(de)(de)油(you)液經配(pei)(pei)油(you)盤(pan)另一窗(chuang)口(kou)(kou)和(he)(he)壓(ya)油(you)口(kou)(kou)1被壓(ya)出(chu)而輸出(chu)到(dao)系統(tong)中去。這種泵(beng)在(zai)(zai)(zai)轉(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)一轉(zhuan)(zhuan)過程(cheng)中,吸油(you)壓(ya)油(you)各(ge)一次,故稱單作(zuo)(zuo)用(yong)(yong)泵(beng)。轉(zhuan)(zhuan)子(zi)(zi)受到(dao)徑(jing)向液壓(ya)不平(ping)(ping)衡作(zuo)(zuo)用(yong)(yong)力(li),故又(you)稱非(fei)平(ping)(ping)衡式泵(beng),其軸承負載較(jiao)大。改(gai)變定(ding)子(zi)(zi)和(he)(he)轉(zhuan)(zhuan)子(zi)(zi)間的(de)(de)(de)偏(pian)心量,便可改(gai)變泵(beng)的(de)(de)(de)排量,故這種泵(beng)都是(shi)(shi)(shi)變量泵(beng)。 二、雙作用葉片泵的工作原理: ATOS葉(xie)片(pian)(pian)泵的(de)作(zuo)用原理和(he)(he)單(dan)作(zuo)用葉(xie)片(pian)(pian)泵相似,不同之處只(zhi)在(zai)于(yu)定(ding)(ding)子表(biao)面是(shi)由兩段(duan)(duan)(duan)長半徑圓弧(hu)、兩段(duan)(duan)(duan)短(duan)半徑圓弧(hu)和(he)(he)四段(duan)(duan)(duan)過渡曲(qu)線(xian)八(ba)個部(bu)分(fen)組(zu)成,且(qie)定(ding)(ding)子和(he)(he)轉(zhuan)(zhuan)子是(shi)同心的(de)。在(zai)圖示轉(zhuan)(zhuan)子順時針(zhen)方向(xiang)旋轉(zhuan)(zhuan)的(de)情(qing)況(kuang)下,密封(feng)工(gong)作(zuo)腔的(de)容積在(zai)左上(shang)角(jiao)和(he)(he)右下角(jiao)處逐漸增大(da),為吸(xi)油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu),在(zai)左下角(jiao)和(he)(he)右上(shang)角(jiao)處逐漸減小,為壓油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu);吸(xi)油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu)和(he)(he)壓油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu)之間有(you)一段(duan)(duan)(duan)封(feng)油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu)把(ba)它們隔開。這種泵的(de)轉(zhuan)(zhuan)子每轉(zhuan)(zhuan)一轉(zhuan)(zhuan),每個密封(feng)工(gong)作(zuo)腔完成吸(xi)油(you)(you)(you)和(he)(he)壓油(you)(you)(you)動作(zuo)各(ge)兩次,所以稱為雙作(zuo)用葉(xie)片(pian)(pian)泵。泵的(de)兩個吸(xi)油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu)和(he)(he)兩個壓油(you)(you)(you)區(qu)(qu)(qu)(qu)(qu)是(shi)徑向(xiang)對稱的(de),作(zuo)用在(zai)轉(zhuan)(zhuan)子上(shang)的(de)液壓力徑向(xiang)平衡,所以又稱為平衡式葉(xie)片(pian)(pian)泵。 雙作用(yong)葉(xie)片泵的(de)瞬時流量是脈(mo)動的(de),當葉(xie)片數(shu)為4的(de)倍數(shu)時脈(mo)動率小。為此(ci),雙作用(yong)葉(xie)片泵的(de)葉(xie)片數(shu)一般都取12或16。 意大利進口ATOS葉片泵部分型(xing)號: PFE-31028/1DV PFE-31036/1DT PFE-31036/1DU 20 PFE-31036/1DV 20 PFE-31036/1DW PFE-31044/1DT 20 PFE-31044/1DU 20 PFE-31044/1DV 20 PFE-32028/3DT 20 PFE-32028/3DV 20 PFE-32036/3DT PFE-41037/1DU 20 PFE-41045/1DT PFE-41045/1DU 20 PFE-41045/1DW 20 PFE-41056/1DT PFE-41056/1DU 20 PFE-41056/1DV 20 PFE-41056/1DW 20 PFE-41070/1DT PFE-41070/1DV 20 PFE-41070/2DT 20 PFE-41070/2DV 20 PFE-41085/1DT 20 PFE-41085/1DW 20 PFE-42045/3DW 20 PFE-42056/3DU 20 PFE-42070/3DT 20 PFE-42070/3DU PFE-42070/3DW 20 PFE-42070/7DV PFE-51090/1DT 23 PFE-51090/1DU PFE-51110/1DT 23 PFE-51110/1DU 23 PFE-51110/3DT 23 PFE-51129/1DT PFE-51150/1DT PFE-51150/3DV PFE-52090/3DT 31 PFE-52110/3DT 31 |
